Vishay IHLP Commercial Inductors, Low DCR Series
The Vishay IHLP-4040DZ-11 series offers low DCR commercial inductors with shielded construction, capable of operating up to 1.0 MHz. These inductors provide the lowest DCR/H in their package size, handle high transient current spikes without saturation, and exhibit ultra-low buzz noise due to their composite construction. They also offer excellent temperature stability for inductance and saturation. Designed with the IHLP technology, these inductors are suitable for various applications including PDA/notebook/desktop/server systems, high current POL converters, low profile/high current power supplies, battery-powered devices, and DC/DC converters in distributed power systems and for FPGAs.

Notes
- All test data is referenced to 25 C ambient.
- Operating temperature range: -55 C to +125 C.
- The part temperature (ambient + temp. rise) should not exceed 125 C under worst-case operating conditions.
- Rated operating voltage (across inductor) = 50 V.
- (1) DC current (A) that will cause an approximate T of 40 C.
- (2) DC current (A) that will cause L0 to drop approximately 20 %.
